Patents by Inventor M. Cameron Sullards

M. Cameron Sullards has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus of uniform gas-phase molecular matrix deposition for imaging mass spectrometry
    Patent number: 7880139
    Abstract: Disclosed are apparatus and methods for depositing solvent-free molecules on surfaces of samples, with particular application to imaging mass spectrometry. A vacuum chamber is configured to have controllable matrix translation apparatus for controlling the position of one or more solvent-free matrices within the chamber. Sublimation apparatus is used to sublimate molecules from the solid phase matrices. One or more samples are placed separately from the solvent-free matrices within the chamber. Condensation apparatus individually cools the samples to deposit sublimated molecules on the samples. Controllable sample translation apparatus is used to control the position of the samples within the chamber. Rotatable sample holding apparatus may be used to hold and move the samples to allow deposition of molecules on multiple samples at substantially the same time.
